Sen. Bernie Sanders, I-Vt., said James Hodgkinson, the man suspected of shooting Rep. Steve Scalise and others, reportedly volunteered on his presidential campaign.
A video of Sanders breaking the news to his Senate colleagues was posted on Twitter by ABC News.
"I have just been informed that the alleged shooter at the Republican baseball practice this morning is someone who apparently volunteered on my presidential campaign," Sanders said. "I am sickened by this despicable act. And let me be as clear as I can be, violence of any kind is unacceptable in our society and I condemn this action in the strongest possible terms."
